The Schedule referred to 1n .these Letters1 Patent and making part of the same.

To all whom it may concern Be it known that'I, WILLIAM H. BERGER, of Pittsburg, in the county otlAllegheny, and State of Pennsylvania, have invented certain new and; useful Improvements in -Machines for Graining and Ornamentin'g Hollow Ware; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification, and to the letters of reference: marked thereon, like letters indicating like parts wherever they occur.

To enable others skilled in the art to construct and use my invention, I will proceed to describe it.

My'invention relates to machines for graining and ornamentiug hollow ware;. and

It consists iin mounting the dieor printing-roller,

. with the apparatus for supplying it with coloring-matter. in the same framey-aud then mounting the. 'frameon a post, arranged to vibrate or rock, so that it may have two motions, one a rotatory motion on the post, and theother a vibratory motion with the post.

It also consists in applying -a scraper, with cloth facing to the distributing-roller, and in operating the printing and distributing or other rollers by friction, as hereinafter explained.

' In the d'rawings- Figure l is a vertical section of my machine, on the A Figure 2 is a top plan view, with a part broken away. v

In constructing my machine, Imake ata-ble or bench,

A, of suitable height and dimensions, and cnt-therein two slots or. openings, a and b, as shown in the figures, and in the slot c mount a post, E, having a stem long enough to project through the table, and receive a key, d, or other suitable device for wedging and holding it firmly in position, and also to allow the post to be adjusted laterally in the slot, when desired.

The upper end of the post E,.I provide with a journal-box, e, or otherV suitable bearing, and mount therein a short shaft having a chuck, F, of the desired shape and dimensions, for receiving the pail, tub, or other article, P, to be grained or ornamented, attached to one end, and to the other a crank-handle, G, for operatiug it.

In the slot or opening 11,1 place a post, D, and pivot its lower end to a bar, B, arranged to move longitudinally, when desired, in vertical supports c, which are firmly attachedto the under side`ot the table, and in -line with the slot b, as clearly shown in fig. l.

' The post D ismade soasto vibrate in the slot b, and the limit of its motionl may be fixedv by means of lthe adjustable guard j, with its set-screw'g. Its upper .endl I provide with a circular head, h, and projecting shoulder fi, having a fstop, j, projecting outward from its periphery, as shown in dotted lines in fig. 2, and upward, as shown in fig. 1. On the post D, I mount a frame, H,having arranged` therein a die or printing-roller, I, having a plain, smooth elastic surface for painting, varnishing, &c., or a raised, figured elastic surface forgraining or ornamenting the hollow ware to which it may be applied; also a distribu'tingdoller, J, made of metal, or having a metallic surface for distributing the coloringmatter on the printing-roller; also a metallic or other suitable scraper, K, with a cloth facing, m, Vfor regulating the quantity of 'coloring-,matter on the distributing-roller and making it uniform, together with a more.. counter-rollers may be arranged between the:

distributing-roller and the coloring-matter, for carrying it to the distributing-roller. l

v The scraper K is made adjustable by means of the set-screws l and n, as shown in both figures.

The front end of the'frame H, Iprovide with an arm, M, curved as shown in the figures, and provided with a handle, N, for operating the frame; f

The under side of this frame I provide with a socket, 0, into which the head h of the post D enters, so that the frame may rotate easilyabout it, its rotation being limited by the stop i coming-in contact with thestops p, as shown in dotted lines in fig. 2, or byany other suitable device.

' In operating my machine, I place the pail, tub, or-

other article to be grained or ornam'euted,on the-chuck F, put the colon'ng-material to be used iu the reservoir L, and adjust the scraper-plate K; then take-hold of the handle N with one hand, and swing or draw-theframe H on the post D forward, till the printing-roller I comes in contact with the surface of the article on the chuck, and with the other, turn the crank-handle G, when the friction between the surfaces of the pail, or other article on the chuck, -and the printing-roller,

`printing-roller *shall* come in contact with all parts of it. As the surface-'of the article to be painted or orhamented is not always uniform, and as the chuck and printing-roller may notalways have `their surfaces exactly parallel, it is found impossible to do good work without this rotating motion of the printing-roller.

It is also necessarythat the distributing-,roller have a metallic surface, so as to be perfectly smooth, and be uniformly and evenly scraped ,by the metallic scraper K, with vits cloth facing m, in order that the supply of -as to accommodate the machines .toarticles of different sizes.

's soon asV one article is finished, the frame H is shoved back, as shown by the red lines in fig'. 1, and another article is placed' on the chuck and finished, and so on. person can easily and rapidly paint, grain, and ornament hollow ware.

I am aware thata machine has been made, in which the printingroller is hung alone in journals, and swung by means of a rock-shaft, operated by a foot-lever, first against a stationary distributing-roller, for receiving its supply of coloring-matter, and then against the article ou the chuck.

I am also aware that it has been suggested, that instead of having a person to paint thedistributingroller', a counter-roller might be revolved by contact In this way it will be seen that a single What I d'o claim, and' desire to secure by Letters Ihatent, is-

1. Arranging the printingroll'er, with the apparatus.

for' supplying it with coloring-matter, in aA frame, and then swivelling this frame -on a vibrating or` rocking post, so that it rnay.haveA rotatory and vibratory motion, substantially as herein described, and for the 4purpose set forth.

2. The adjustable metallic plate K, provided' with a cloth' facing, m, in combination with the distributingroller J, constructed and arranged to operate substantially as herein described, and for the puspose set forth.

3. 'llhe post E and bai` B, when constructedfand' arranged so as to be adj uste'd laterally, substantially as herein described, for the purpose 'of adapting the machine for graining diiferent-sized articles, as s'et forth. s
